I went to a BC "talk" last night and asked the onc. surgeon why originally folks were asked to take Femara for 5 years and then it went up to 10. He stated that there is new research and now they're saying 5 is good enough. Has anyone else heard of this? I've been on it for 6 years and have heard it's hard to lose weight and increases cholesterol (which has happened to me) and I was hoping to get off it.
